Effect

In battle

Generations IV and V

Frisk allows the Pokémon to see the opponent's held item upon entering battle. If the foe is holding an item, a message identifying the item will be shown right after the Pokémon with Frisk enters the battle. If the foe is not holding an item, no message will appear.

In a Double Battle, an unidentified opponent is randomly chosen and their held item revealed.

Generation VI

Frisk now identifies the held items of all opposing Pokémon, regardless of position.
